Study Notes
Definition of Control
- Control refers to the process of regulating or directing the behavior of a system, process, or person to achieve a desired outcome or goal.
- It involves setting standards, measuring performance, and taking corrective action to ensure that the desired outcome is achieved.
Types of Control
- Feedforward control: anticipates and prevents errors or deviations from the desired outcome.
- Feedback control: detects and corrects errors or deviations after they have occurred.
- Concurrent control: monitors and corrects errors or deviations in real-time.
Control Systems
- Open-loop control system: does not use feedback to adjust its behavior.
- Closed-loop control system: uses feedback to adjust its behavior and achieve the desired outcome.
Control Mechanisms
- Regulators: maintain a desired level or condition by adjusting the system's inputs.
- Governors: limit the maximum or minimum value of a variable to prevent excessive or deficient values.
- Sensors: detect and measure the system's state or performance.
- Actuators: implement the control action to correct errors or deviations.
Control in Different Fields
- Management: control is used to achieve organizational goals and objectives.
- Engineering: control is used to design and operate systems, processes, and machines.
- Psychology: control is used to understand and influence human behavior.
- Sociology: control is used to understand and regulate social systems and institutions.
Control Theories
- Classical control theory: focuses on the use of feedback and control algorithms to regulate systems.
- Modern control theory: incorporates mathematical and computational techniques to analyze and design control systems.
- Optimal control theory: seeks to find the optimal control strategy to achieve the desired outcome.
